Stopped by the dealership, test drove the used car...

Stopped by the dealership, test drove the used car that was listed and after some negotiation, with sales person and later manager, agreed to the final price which was lower than the sticker price... We shook hands and I thought it was done deal....5 minutes later manager shows up to tell us that he was unaware that car didn't go through "detailing" and he can not give me "unchecked" car because IRA "thrives" on costumer satisfaction!? Sound amazing, right? He tells me that he thought detailing was done and added that detailing cost money but it has be done, IRA rules, and if they find some issues with a car repair cost will be added to the car price. I told them I was ok with it but it made zero sense that they wanted to charge me more money for detailing which was suppose to be included in original sticker price???? ."All of their cars go through it before reaching the floor" I was told... Anyways, week later I call them back and they tell me that detailing was done, no repair were made except for some standard servicing, oil top-up and wiper replacement.... So I asked them if we are ok with our deal.I was told NO because car was detailed and serviced and they could not give me a deal we had because "new price" for a car is.....wait for it.... The same Original Price Tag that they had in the first place without a "detailing"!? Wow! Mind blowing....with this kind of logic I am happy to shop somewhere else...
